SPRING FOR AUTOMOBILE-TIRES.

To all whom it may concern:

Be it known that I, HERMAN MENN, a citizen of the United States, residing at Dexter, in the county of Chaves and State of New Mexico, have invented a new and useful Springfor Automobile-Tires, of which the following is a specification.

The device forming the subject matter of this application is a spring cushion adapted to replace inner tubes and like elements subject to puncture in a tire.

The invention. aims to provide a device of the type above mentioned in which but two different kinds of springs are employed, the same cooperating in a novel manner to afford unusual strength and resiliency.

It is Within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which .will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of'construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings :-Figure 1 shows the invention in side elevation, parts being broken away; Fig. 2 is a top plan; Fig. 3 is a transverse section onthe line 33 of Fig. 1; Fig. f is a perspective delineating one of the primary springs; Fig. 5 is a perspective delineating one of the secondary springs.

In carrying out the present invention there is provided a rim 1. The invention includes a plurality of arched or curved primary springs 2 each comprising a tread 15 having an opening 3, a reduced tongue 1 projecting from one end of the tread l5, and a foot 5 projecting from the other end of the tread. When the primary springs 2 are mounted on the rim 1, all of the tongues 4: project in a common direction circumferentially of the The invention includes arched or. curved secondary springs 6 each comprising a reduced tongue 7 and a foot 8. When the secondary springs 6 are assembled with the rim 1, all of the tongues 7 project in a common direction, and these tongues project in Specification of Letters Patent. Patggntygd J 1y 2?, 1915.

an opposite direction to the tongues 4t of the primary springs 2.

The feet 5 and 8 of the respective springs are equipped with openings 9. The feet 5 of the primary springs 2 rest immediately on the rim 1, the feet 8 of the secondary springs 6 being superposed on the feet 5, and the feet of both of the springs being held to the rim 1 by means of securing elements 10 of any desired sort.

As indicated at 11, the tongue l of one primary spring 2 extends beneath the tread 15 of an adjoining primary spring through the opening 3. As shown at 14, the tongue 7 of each secondary spring extends beneath the tread 15 of an adjoining primary spring, through the opening 3. As indicated at 16, the tongues 7 of alternate secondary springs liev between the tread 15 of one primary spring and the tongue 4: of an adjoining primary spring. As shown at 17, the tongues 7 of the remaining, alternate secondary springs lie beneath the tongues 4 of the primary springs, the tongues 4: under such circumstances being interposed between the treads 15 of the primary springs and the tongues 7 of the secondary springs.

Those skilled in the art will understand, without specific illustration, that the cushion herein disclosed preferably is employed in connection with a tire casing of any desired sort which need not be shown.

The spring structure forming the subject matter ofthis application comprises a minimum number of parts, in that only two different kinds of, springs are employed, yet these springs, owing to the manner in which they cooperate, give to the structure a maximum resiliency combined with adequate strength.

Having thus described the invention, what is claimed is 1. In a device of the class described, a rim; primary springs secured to the rim and extended in one direction circumferentially 1 of the rim, each primary spring having an opening and comprising a tread and a reduced tongue, the tongue of onev primary spring being extended beneath the tread of an adjoining primary spring through the opening therein; and secondary springs secured to the rim and extended in an opposite direction circumferentially of the rim, each secondary spring comprising a reduced tongue extended through the opening in one of the primary springs beneath the tread thereof, the tongues of the secondary springs lying alternately above and below the tongues of the primary springs.

2. In a device of the class described, a rim; primary springs secured to the rim and extended in one direction circumferentially of the rim, each primary spring having an opening and comprising a tread and a reduced tongue, the tongue of one primary spring being extended beneath the tread of an adjoining primary spring through the opening therein; and secondary springs secured to the rim and extended in an opposite direction circumferentially of the rim, each secondary spring comprising a reduced tongue extended through the opening inone of the primary springs beneath the tread thereof and being overlapped upon the tongue of the primary spring circumferentially.

3. In a device of the class described, a rim; primary springs secured to the rim and extended in one direction circumferentially of the rim, each primary spring having an opening and comprising a tread and a reduced tongue, the tongue of one primary spring being extended beneath the tread of an adjoining primary spring through the opening therein; and secondary springs secured to the rim and extended in an opposite-direction circumferentially of the rim, each secondary spring comprising a reduced tongue extended through the opening in one of the primary springs, beneath the treadthereof.

4:. In a device of the class described,' a rim; primary springs secured to the rim and extended circumferentially of the rim, each primary spring having an opening and'comprising a tread, the end of onev primary spring being extendedbeneath the-tread of an adjoining primary spring through the opening thereln; and secondary springs secured to the rim and extended in an opposite direction circumferentially of the rim, one end of" each secondary spring being extended through the opening in one of the primary springs beneath the tread thereof.

5. In a device of the class described, a rim; primary springs secured to the rim and extended circumferentially of the rim, each primary spring having an opening and comprising a tread, the end of one primary spring being extended beneath thetread of an adjoining primary spring through the openingtherein; and secondary springs secured to the rim and extended in an opposite direction circumferentially of the rim, one end of each secondary spring being extended through the opening in one of the primary springs beneath the tread thereof, the-ends of the secondary springs lying al ternately' above and below the ends of the primary springs.

6. In a device of the class described, a rim; primary springs secured to the rim and extended circumferentially of the rim, each primary spring having an opening and comprising a: tread, the end of one primary spring being extended beneath the tread of an adjoining primary spring through the opening therein; and secondary springs secured to the rim and extended in an opposite direction circumferentially of the'rim, one end of each secondary spring being; extended through the opening in; one of the primary. springs beneath the tread thereof, the ends of the primary and secondary springs being overlapped upon each other.

In testimony that I claim the foregoing asmy own, I havehereto afiixedmy signature inthe presence of two Witnesses.
